YamaTough told Freed the account data is just a sample of the information the hacker group, the "Lords of Dharmaraja," copied from Indian government servers.

"In the best interest of the federal, state and local municipalities and their constituents, Infosec Island will not publish the compromised account data," Freed wrote. "We have provided the information to the proper authorities and are fully cooperating with law enforcement."

As a possible demonstration of the viability of those backdoors, the memos also included transcripts of emails between members of the U.S.-China Economic and Security Review Commission (USCC), a congressional commission that analyzes and reports on bilateral American-Chinese relations. The memos said information revealed in the emails had resulted in Indian naval-intelligence operatives being sent to China.

Reuters said it got hold of a larger set of USCC emails, which it showed to two Indian security experts with ties to India's government and two unnamed Americans "close to" the USCC. All four dismissed the memos as hoaxes possibly concocted by China or India's arch-rival Pakistan.

Other Washington insiders told Reuters the memos seemed genuine.

America, heck yeah

Asked about the Lord of Dharmaraja's motives, YamaTough responded with a strikingly pro-American agenda.

"My team is pro US, we fight for rights in our country we are not intentionally harm US companies," Freed quoted him as writing. "Our mission - exposure of the corruption."
